WASHINGTON (AP) — Health workers on the front line of the Ebola crisis say the need for urgent help isn't letting up. They are making that pitch as Congress begins considering President Barack Obama's $6.2 billion emergency aid request to fight the disease.

Despite reports that the number of infections is slowing in some parts of West Africa, cases still are rising in other areas. Aid organizations say thousands of health care workers are needed to treat Ebola over the next few months.

On Wednesday, the Senate Appropriations Committee plans to question Obama administration officials about the U.S. response to the Ebola outbreak as it evaluates the emergency aid request.
